如何在菜单项选择SwiftUI时设置复选标记

import SwiftUI

struct ContentView: View {
    @State private var isChecked = false

    var body: some View {
        VStack {
            Menu {
                MenuItem("Option 1", action: {
                    // Handle option 1 selection
                })
                MenuItem("Option 2", action: {
                    // Handle option 2 selection
                })
                MenuItem("SwiftUI", action: {
                    isChecked.toggle()
                })
                    .checkbox(isChecked: $isChecked)
            } label: {
                Label("Menu", systemImage: "ellipsis")
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
